Woodhouse's Toad

Fascinating facts about the Woodhouse's Toad

• The male Woodhouse's toad produces a brief call that sounds like a sheep bleating, lasting only one to three seconds. He does this from, or very close to, standing water where breeding takes place. The call is emitted through a single vocal sac on his throat, a feature that distinguishes the male during the breeding season. This short, distinctive sound helps females locate a mate in the nocturnal breeding ponds.
• Woodhouse's toad will interbreed with the American toad wherever their geographic ranges intersect, producing hybrid offspring. This hybridisation occurs naturally in the overlap zones of their distributions. The species itself is divided into three recognised subspecies, reflecting its broad range across North America. Such genetic mixing is part of the toad's complex taxonomic history.
• Woodhouse's toad is a nocturnal predator that hunts insects and other small invertebrates after dark. Near human settlements it often gathers beneath outdoor lights, taking advantage of the insects drawn to the illumination. This behaviour allows the toads to feed efficiently in urban and agricultural landscapes. Their diet and night-time activity help them thrive in a variety of habitats.
• The species inhabits elevations up to 2,500 metres, spanning from Mexico northward to Washington state. It occupies lowland streams as well as high-altitude wet meadows. In the western part of its range it is typically found in lowland riparian corridors and wooded land beside streams and rivers, while at higher altitudes it lives in wet meadows, ponds, reservoirs and lakes. This broad altitudinal and habitat use allows it to thrive across a wide geographic area.
• In central Arizona it seems to be displacing or hybridising with the Arizona toad (Anaxyrus microscaphus). The toad has a very wide range and a presumed large total population, and it can live in many habitat types, tolerating some modification to its environment. The population appears steady and no particular threats have been identified. Consequently the International Union for Conservation of Nature has assessed it as being of least concern.

About the Woodhouse's Toad

In the arid landscapes of the American Southwest, the Woodhouse's toad emerges as a paradox of vulnerability and resilience, its warty skin a testament to the harsh realities of its desert home. As it moves through the world, this unassuming amphibian navigates a delicate balance of moisture and heat, its nocturnal wanderings a quest for sustenance and connection in a land of sparse rainfall and scorching sun. With its remarkable ability to estivate, sealing itself within a waterproof cocoon to await the return of life-giving rains, the Woodhouse's toad has evolved a remarkable strategy for survival in one of the most unforgiving environments on Earth.
